This is just something I dreamed up based on the UFO theme
Cyber Saucer (6900/6999) kit.  It resembles the Warp Wing
Fighter (6915) but I tried to make it look more squat and
menacing.  The twin gatling guns help - they track each other
on a modified rack & pinion steering system.  The rear landing
gear are linked to the wings - "gear up = wings down" and vice
versa.  See the LDraw pix for the (simple) mechanism.
